The results of the publication bias test showed that a developmental bias in the effective rate. Further analysis based on the non-parametric clipping and supplementation method showed stable results of meta-analysis and no impact from potential publication bias. The adverse reactions had no statistically significance. Conclusion:This study shows that Tanreqing injection has a significant effect in treating chronic bronchitis in the elderly，and can reduce the serum CRP level of the patients. Compared with the conventional therapy group，the incidence of adverse reactions is not significantly increased，and the results need further clinical tests.

Mechanism of Qingke Pingchuan Granule in Treatment of Acute and Chronic Bronchitis Complicated with Chronic Obstructive Pulmonary Disease： An Exploration Based on Network Pharmacology / 中国实验方剂学杂志

Objective:To explore the potential mechanism of Qingke Pingchuan granule in treating acute and chronic bronchitis complicated with chronic obstructive pulmonary disease （COPD） by network pharmacology. Method:The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） was retrieved to collect the active components of Qingke Pingchuan granule and predict the action targets， followed by the construction of component-target network using Cytoscape 3.8. GeneCards， Online Mendelian Inheritance in Man（OMIM）， and DrugBank were used to harvest disease targets， whose names were put into UniProt for standardization. The treatment targets of Qingke Pingchuan Granule against the two diseases were obtained based on Venn diagram， which were then imported into the STRING platform for constructing the protein-protein interaction （PPI） network. Following the gene ontology（GO） and Kyoto encyclopedia of genes and genomes（KEGG） pathway enrichment analysis based on MetaScape， the active component-common target-signaling pathway network of Qingke Pingchuan granule against acute and chronic bronchitis complicated with COPD was finally constructed. The accuracy of the target was confirmed by literature. Result:A total of 165 active components， 374 related targets， 512 disease-related targets， and 130 common targets were obtained. Among them， the 14 core therapeutic targets were further subjected to GO enrichment analysis， which yielded 390 biological processes， nine cell components， and 23 molecular functions. The KEGG pathway analysis revealed 22 signaling pathways. Conclusion:Qingke Pingchuan granule alleviates the diseases possibly by regulating such targets as vascular endothelial growth factor receptor 2（KDR）， transforming growth factor beta-1 （TGF-<italic>β</italic>₁）， caveolin 1（CAV1）， hypoxia-inducible factor-1alpha（HIF-1<italic>α</italic>）， and interleukin-2（IL-2）， affecting the synthesis and transport of regulatory factors in cytoplasm， and controlling the cell proliferation and apoptosis.

Effect of fresh Phragmitis Rhizoma on airway inflammation in chronic bronchitis based on TGF-β signaling pathway / 中国中药杂志

This study aims to explore the mechanism of fresh Phragmitis Rhizoma against chronic bronchitis airway inflammation. The SD rats of SPF grade were divided into control group, model group, Guilongkechuanning group(GLKCN, 1.125 g·kg~(-1)), high-dose fresh Phragmitis Rhizoma group(LG-HD, 15 g·kg~(-1)), and low-dose fresh Phragmitis Rhizoma group(LG-LD, 7.5 g·kg~(-1)). The chronic bronchitis models of rats in other groups except the control group were induced by the modified smoking method. From the 15 th day of modeling, the rats were given corresponding agents by gavage for 20 consecutive days. After the last administration, the rats were sacrificed for sample collection. Enzyme-linked immunosorbent assay(ELISA) was employed to detect serum transforming growth factor-β(TGF-β) and interleukin-6(IL-6) levels. The protein expression of TGF-β, IL-1β and IL-6 in lung tissue was detected by immunohistochemical method. Masson staining was performed to detect collagen fibers and muscle fibers in lung tissue, and HE staining to detect the pathological changes of lung tissue. Human bronchial epithelial(16 HBE) cells were cultured in vitro, and CCK-8(cell counting kit-8) method was used to detect the cytotoxicity of cigarette smoke extract(CSE) and fresh Phragmitis Rhizoma. After the exposure of 16 HBE cells to 3.5% CSE and appropriate concentration(800, 400 μg·mL~(-1)) of fresh Phragmitis Rhizoma for 24 h, quantitative real-time PCR was conducted to determine the mRNA levels of TGF-β and IL-1β, and Western blot was employed to determine the protein levels of TGF-β and IL-6 in the cells. The rat model of chronic bronchitis induced by smoking was successfully established. Fresh Phragmitis Rhizoma reduced serum TGF-β and IL-6 levels, down-regulated the protein levels of TGF-β, IL-1β, and IL-6 in lung tissue, and alleviated pathological changes and fibrotic lesions in lung tissue. Moreover, it down-regulated the CSE-induced protein expression of TGF-β and IL-6 as well as the mRNA level of TGF-β in 16 HBE cells. These results indicated that fresh Phragmitis Rhizoma could prevent airway inflammation from chronic bronchitis and promote cell repair by inhibiting the TGF-β signaling pathway.

Preventive and therapeutic effects and mechanism of Xiaoer Feike Granules on chronic bronchitis induced by lipopolysaccharide in rats / 中国中药杂志

The aim of this paper was to investigate the preventive and therapeutic effects of Xiaoer Feike Granules(XEFK) on chronic bronchitis in rats and its mechanism. Except for 10 rats in the blank group, the remaining 50 of the 60 SD rats were used to establish a model of chronic bronchitis induced by LPS. On the 22 nd day, the model rats were randomly divided into 5 groups according to their body weight, and administrated with purified water, Keteling Capsules 0.11 g·kg~(-1), XEFK 3.2, 1.6 and 0.8 g·kg~(-1)(the dosing concentrations were 0.32, 0.16, 0.08 g·mL~(-1), respectively). These rats took the corresponding drug orally once a day, for consecutive 21 days. The rats were anesthetized 1 hour after the last administration, and the lavage bronchus and alveoli were collected. Then, after the fixation of the smear, neutrophils were counted microscopically, and the contents of glutathione peroxidase(GSH-Px), superoxide dismutase(SOD) and malondialdehyde(MDA) in the bronchoalveolar lavage fluid(BALF) were detected by colorimetric method. Flow cytometry was used to detect the content changes of T cell subsets CD4~+, CD8~+, CD4~+/CD8~(+ )in serum. Hemorheology related indexes were detected by automatic hemorheology. Enzyme-linked immunosorbent assay(ELISA) was used to detect the contents of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), IL-2, IL-6 and IL-10 in serum. The expression of TNF-α and IL-10 mRNA in lung was detected by Real-time quantitative PCR(RT-qPCR). HE staining was used to observe the pathological changes in the bronchitis tissues. Compared with the model group, XEFK high and medium dose groups could significantly reduce the contents of neutrophils and MDA in bronchial lavage fluid, and increase the activities of GSH-Px and SOD in BALF, and repair the chronic inflammatory cell infiltration and lymphoid tissue hyperplasia in the bronchial mucosal layer and submucosal layer. The high-dose group could reduce the plasma viscosity of rats, but there was no statistical difference in other hemorheological indexes. CD4~+, CD8~+, CD4~+/CD8~+, IL-2 and IL-10 contents in each dose group were significantly increased, and TNF-α, IL-1β and IL-6 contents were significantly decreased in serum. Each dose group could significantly down-regulate the expression level of TNF-α mRNA in the lung and increase the expression of IL-10 mRNA. XEFK could reduce lipid peroxidation, increase the content of peripheral blood T cell subsets, regulate the release and secretion of inflammatory factors, and repair the morphological and pathological changes of bronchial tissue. Its mechanism might be related to the improvement of inflammatory response and the enhancement of immune function.

Isolation and Identification of Total Alkaloids from Mongolian Medicine Aconitum excelsum and Its Therapeutic Mechanism on Chronic Bronchitis in Rats / 中国药学杂志

OBJECTIVE: To isolate and identify the total alkaloids from Aconitum excelsum and to study the therapeutic mechanism of the total alkaloids from Aconitum excelsum on chronic bronchitis in rats. METHODS: The total alkaloids from Aconitum excelsum was isolated by TLC and the structures of compounds were elucidated by a variety of spectral techniques. The rat model of chronic bronchitis (CB) was established with combined utilization of bacillus calmette-guerin and lipopolysaccharide, dexamethasone tablets and total alkaloids from Aconitum excelsum (high and low dose) were ig administrated. The pathological changes of lung tissue in rats were observed by HE and the level changes of interleukin-1 (IL-1), interleukin-8 (IL-8) and tumor necrosis factor-α (TNF-α) in serum were determined by ELISA method. RESULTS: Seven alkaloids were identified from the total alkaloids of Aconitum excelsum. The administration of total alkaloids from Aconitum excelsum could decrease the degree of infiltration, epithelial cell shedding, bronchial secretion, inhibit the proliferation of bronchial epithelial cells of the rat bronchial inflammatory cells, and make the bronchial diameter increases and ventilation. The total alkaloids could significantly inhibit the increase of IL-1, IL-8 and TNF-α in the serum of rats with CB, compared with the model group with the statistical significance (P<0.05). CONCLUSION: The total alkaloids from Aconitum excelsum have the better treatment effect on CB, which may be related to its main chemical components, namely lappaconitine (1), ranaconitine (2), septentriod-ine (3), 6-demethyldelsodine (4), 6-methylumbrofine (5), 8-methyl-10-hydroxylycoctonine (6) and 8-methyllycoctonine (7).

Enfermedad Pulmonar Obstructiva Crónica en el Siglo XXI - Optimismo basado en evidencia / Chronic Obstructive Pulmonary Disease in the 21st Century - Evidence-based optimism

There are increasingly more data on the prevalence and distribution of Chronic Obstructive Pulmonary Disease (COPD) from around the world. COPD is predicted to be the third most frequent cause of death in the world by 2020. COPD is mainly caused by chronic tobacco smoking, which induces important changes in both the airways and lung parenchyma. COPD is a progressive, disabling condition that ultimately ends in respiratory failure and death. Is a multicomponent disease, there is evidence that systemic inflammation and extrapulmonary effects are also common in COPD, although the association between systemic inflammation and systemic manifestations of COPD is still not entirely clear. COPD has been associated with a nihilistic attitude. On the basis of current evidence, this nihilistic attitude is totally unjustified. The disease must be viewed through the lens of a new paradigm: COPD is not only preventable but also treatable. The past decade has witnessed great progress in COPD research. New drugs have been developed and tested and a growing base of scientific evidence now documents the efficacy of various therapies for symptoms and exacerbations. It is clear that many patients with COPD can benefit from aggressive management, with a decrease in the frequency of hospitalizations and improvements in symptoms and quality of life. In addition, basic and clinical scientists have now identified cells, mechanisms, and molecules that appear to play key roles in disease pathogenesis. Additional novel treatments are on the horizon and the advent of newer and more effective therapies will lead to a decline in the contribution of this disease to poor world health. The good news about COPD is to increase awareness of the disease. COPD is now viewed under a new paradigm as preventable and treatable.

Analysis of clinical features and inflammatory factors in induced sputum in common phenotypes of COPD with frequent exacerbations / 中国综合临床

Objective To compare the clinical characteristics of chronic bronchitis ( CB),emphysema (EM ), asthma - chronic obstructive pulmonary disease overlapping syndrome ( ACOS ) with frequent exacerbations ( FE ) or infrequent exacerbations ( iFE ) and induced sputum inflammatory cells and the heterogeneity of the transmitter. Methods Ninety-one cases of chronic obstructive pulmonary disease( COPD) with acute exacerbation were divided into CB,EM or ACOS phenotype,among which 44 were frequent,and 47 were non frequent. The clinical data,induced sputum inflammatory cells,interferon-γ(IFN-γ),tumor necrosis factor-α ( TNF-α ), interleukin ( IL )-4, IL-13 were analyzed. Results The FEV1% was ( 47 ± 13. 1 )%, significantly lower than that of non frequent episodes (( 56. 2 ± 10. 2)%),and the difference was statistically significant(P＝0.049).The FEV1/FVC% was (54.3±9.3)%,significantly lower than that of non frequent episodes (60. 1±7. 3)%,and there was a significant difference between them ( P＝0. 001) . The proportion of patients with GOLD III and IV,the percentage of neutrophils in induced sputum,tumor necrosis factor -α(TNF-α) and interferon-γin the patients with frequent episodes were significantly higher than those with non frequent episodes (P＜0. 05). Among them,FEV1/FVC% and TNF-αwere independent risk factors for COPD patients (P＝0. 032, 0. 021) . The FEV1% of patients with CB phenotypic frequent episodes were ( 47. 9 ± 14. 9 )%, significantly lower than that of non frequent episodes ((57. 2±10. 9)%)(P＝0. 000),and FEV1/FVC% was (53. 4± 9. 5)% in patients with CB frequent episodes,significantly lower than that of non frequent episodes ((60. 3±6. 9)%),and the difference was statistically significant (P＝0. 022),while the level of N%,TNF-α in induced sputum were significantly higher in CB phenotype subjects with FE than those in subjects with iFE(P＜0. 01). Patients with frequent episodes of emphysema had longer duration of disease (P＜0. 05),lower FEV1%and FEV1/FVC%(P＜0. 05),the proportion of GOLD III patients and the induced sputum TNF-αwere higher, but there was no significant difference in the number and proportion of phlegm inflammatory cells,interferon-γ, interleukin 4 and interleukin 3. The level of GOLD III and the IL-13 level of induced sputum in patients with frequent ACOS phenotype were significantly higher than those in patients with non frequent episodes (P＜0. 05) . Conclusion The lung function,the severity of the disease,the course of the disease,and the percentage of sputum neutrophils,tumor necrosis factor-α,or interleukin 13 are helpful in diagnosing patients with high risk of frequent episodes.

Medication rules of famous veteran traditional Chinese medicine doctor in treatment of chronic bronchitis based on implicit structure model / 中国中药杂志

To explore the medication rules of famous veteran traditional Chinese medicine (TCM) doctors in treatment of chronic bronchitis, a structured medical record database for famous veteran TCM doctors in modern clinical books was established. First, Lantern 3.1.2(Kongmin light) implicit structure analysis software was used to build an implicit structure model and make an implicit interpretation. Then, SAS 9.1 was adopted to mine herb-herb, herb-symptom and herb-syndrome association rules. Through the mining, 1 274 commonly used herbs for chronic bronchitis were found, including liquorice, bitter almond, pinellia, dried tangerine or orange peel, poria cocos. The medicine types included antiasthmatic medicine, qi-tonifying medicine, and heat-phlegm removing medicine. The medicine tastes included sweet, pungent and bitter. The meridian distributions included lung, spleen and stomach channels. The famous commonly used prescriptions included Xiaoqinglong decoction, Maxing Shigan decoction and Erchen decoction. The 147-herb implicit structure model for the first diagnosis was built to get 44 hidden variables, 88 hidden classes, 7 comprehensive clustering models, 9 dual herb associations, 50 triple herb associations and 89 quadruple associations. Totally 297 medical records for the second diagnosis were compared to obtain 24 herb-symptom associations, which reduced ephedra, bitter almond, pinellia and added poria cocos, atractylodes, dangshen, 20 dual herb associations and 8 triple herb associations. A model for the top 83 symptoms and top 96 herbs in the first diagnosis was built to get 50 hidden variables and 101 hidden classes. The commonly used herbs of famous veteran TCM doctors included bitter almond, pinellia, dried tangerine or orange peel, poria cocos, which feature mild property and sweet favor and enter lung, spleen, kidney meridians; the commonly herbal pairs included atractylodes and poria cocos, asarum, fructus schisandrae and pinellia, as well as poria cocos, dangshen, pinellia and dried tangerine or orange peel. The herb-syndrome associations involved ephedra, bitter almond, cassia twig and scanty sputum, pinellia and external cold and internal fluid syndrome, turbid phlegm obstructing lung syndrome and spleen deficiency syndrome, bitter almond and turbid phlegm obstructing lung syndrome, phlegm-heat accumulated in the lung and wind-cold invading the lung. The implicit structure model can be used to quantify tacit knowledge of TCM, extend to the herb and syndrome level for the first time, and quantify the major, minor and compatible statues of different variables in the same data. This study concluded that the medication rules of famous veteran TCM doctors in treatment of chronic bronchitis have certain reference value for the clinical diagnosis and treatment. The data sources, analysis methods and mining results were relatively reliable and objective, and can provide a reference for rules of other disease treatment based on syndrome differentiation.

Neutrophil extracellular traps induce production of MPO-ANCA in chronic bronchitis rats / 中国免疫学杂志

Objective:To investigate the mechanism of chronic bronchitis with recurrent long duration infections in the production of MPO anti-neutrophil cytoplasmic antibodies(ANCA). Methods:Rats were gave intratracheal injection of LPS and smoked to established chronic bronchitis ( CB ) model. Rat neutrophils were incubated with phorbol-12-myristate-13-acetate ( PMA ) to induce Neutrophil extracellular traps(NETs). NETs were then used to immune chronic bronchitis rats. Serum concentrations of myeloperoxidase anti-neutrophil cytoplasmic antibodies(MPO-ANCA),Citrullinated Histone H3(CitH3),Interferon-α(IFN-α)were evaluated. Results:(1)The serum levels of MPO-ANCA in chronic bronchitis rats immuned with NETs(CB/NETs)were significantly higher than those in chronic bronchitis rats(CB)and healthy control rats,(62. 4975±19. 63764)ng/ml vs (17. 3806±4. 88649)ng/ml,(20. 8884± 4. 39607)ng/ml(both P<0. 01). (2)The serum levels of CitH3 in CB/NETs rat were significantly higher than those in CB rat and healthy control rats,(32. 5974±20. 2915)ng/ml vs (8. 8568±2. 36692)ng/ml,(5. 6225±0. 83738)ng/ml(P<0. 05,P<0. 01). (3)The serum levels of IFN-α were found increased sharply in two CB/NETs rats(3735.7,3428.4 pg/ml). (4)Renal function among three groups showed no significant difference yet. ( 5 ) Serum CitH3 level showed a positive correlation with serum MPO-ANCA level(r=0. 61,P<0. 05). Conclusion:Chronic bronchitis with recurrent infections could induce the production of ANCA probably by the stimulation of NETs,but whether it might develop to AAV remains need a duration.

The clinical therapeutic effect of N-acetylcysteine on chronic bronchitis: a Meta-analysis / 中国中西医结合急救杂志

Objective To observe the clinical therapeutic efficacy of N-acetylcysteine (NAC) on chronic bronchitis. Methods The data were retrieved by computer from data bases, including the data bases in Cochrane library, American National Library Pubmed, Holland Medical Digest EMBase, Web of Science, China National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), Wanfang and the Chinese Journal of Science and Technology (VIP), starting from the dates of various database establishments to April 2017 for collecting the randomized controlled trials (RCTs) of using NAC combined with conventional drugs like ambroxol hydrochloride, montelukast or placebo (treatment group) and simply using the conventional drug alone as above conventional drugs (control group) for treatment of chronic bronchitis, and the therapeutic effects were compared between the two groups. The main indicators were total effective rate, lung function indexes [forced vital capacity (FVC), percentage of forced expiratory volume in one second (FEV1) / the predictive value (FEV1%)]; the secondary indicator was St. George Hospital Respiratory Questionnaire evaluation score (the SGRQ evaluation score). Document quality evaluation and data acquisition were carried out independently by two researchers. Meta-analysis was performed by using RevMan 5.3 software. A funnel graph was drawn to evaluate the article publication bias. Results There were 7 Chinese and 3 English RCTs, including 1521 patients in the study. The results of Meta analyses showed: NAC could elevate the overall therapeutic efficiency of patients with chronic bronchitis [relative risk (RR) = 1.17, 95% confidence interval (95%CI) was 1.10-1.25, P < 0.00001], FVC [mean difference (MD) = 0.22, 95%CI was 0.02-0.42, P = 0.03), FEV1% (MD = 4.10, 95%CI was 1.02-7.18, P = 0.005) and lower the SGRQ score (MD = -6.32, 95%CI was -10.48 to -2.17, P = 0.003), showing that the therapeutic effects on these aspects in using NAC treatment group were more prominent than those in the control group. The subgroup analyses showed that NAC combined with ambroxol hydrochloride could elevate overall therapeutic efficiency (RR = 1.20, 95%CI was 1.11-1.29, P <0.00001), FVC (RR = 1.18, 95%CI was 0.99-1.41, P = 0.04) and FEV1% (MD = 4.10, 95%CI was 1.02-7.18, P = 0.005), showing that the therapeutic effects on these aspects in using NAC combined with ambroxol hydrochloride group were more prominent than those in the control group; the total rate of therapeutic effect of NAC combined with montelukast was superior to that of the control group (RR = 1.12, 95%CI =1.03-1.22, P = 0.006); NAC combined with placebo in elevating FVC aspect was better than the control group (MD =-0.01, 95%CI = -0.02 to -0.01, P < 0.00001); funnel plots showed that no publication bias was found in the literatures in the study. Conclusion It is shown that NAC for treatment of chronic bronchitis can improve the overall therapeutic efficiency, lower the SGRQ evaluation score and elevate the lung function in FVC and FEV1% aspects, but no effect on FEV1/FVC.

Neutrophil extracellular traps induce production of MPO-ANCA in chronic bronchitis rats / 中国免疫学杂志

Objective:To investigate the mechanism of chronic bronchitis with recurrent long duration infections in the production of MPO anti-neutrophil cytoplasmic antibodies(ANCA). Methods:Rats were gave intratracheal injection of LPS and smoked to established chronic bronchitis ( CB ) model. Rat neutrophils were incubated with phorbol-12-myristate-13-acetate ( PMA ) to induce Neutrophil extracellular traps(NETs). NETs were then used to immune chronic bronchitis rats. Serum concentrations of myeloperoxidase anti-neutrophil cytoplasmic antibodies(MPO-ANCA),Citrullinated Histone H3(CitH3),Interferon-α(IFN-α)were evaluated. Results:(1)The serum levels of MPO-ANCA in chronic bronchitis rats immuned with NETs(CB/NETs)were significantly higher than those in chronic bronchitis rats(CB)and healthy control rats,(62. 4975±19. 63764)ng/ml vs (17. 3806±4. 88649)ng/ml,(20. 8884± 4. 39607)ng/ml(both P<0. 01). (2)The serum levels of CitH3 in CB/NETs rat were significantly higher than those in CB rat and healthy control rats,(32. 5974±20. 2915)ng/ml vs (8. 8568±2. 36692)ng/ml,(5. 6225±0. 83738)ng/ml(P<0. 05,P<0. 01). (3)The serum levels of IFN-α were found increased sharply in two CB/NETs rats(3735.7,3428.4 pg/ml). (4)Renal function among three groups showed no significant difference yet. ( 5 ) Serum CitH3 level showed a positive correlation with serum MPO-ANCA level(r=0. 61,P<0. 05). Conclusion:Chronic bronchitis with recurrent infections could induce the production of ANCA probably by the stimulation of NETs,but whether it might develop to AAV remains need a duration.

Conclusion Oxygen atomization inhaler and compression atomizing inhalation atomization inhalation machine for chronic bronchitis is the exact effect in the treatment, two treatment effect significantly, but the oxygen driven aerosol treatment in relieving clinical symptoms and signs of patients with the advantages of better than compression atomizing treatment.

The clinical therapeutic effect of N-acetylcysteine on chronic bronchitis: a Meta-analysis / 中国中西医结合急救杂志

Objective To observe the clinical therapeutic efficacy of N-acetylcysteine (NAC) on chronic bronchitis. Methods The data were retrieved by computer from data bases, including the data bases in Cochrane library, American National Library Pubmed, Holland Medical Digest EMBase, Web of Science, China National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), Wanfang and the Chinese Journal of Science and Technology (VIP), starting from the dates of various database establishments to April 2017 for collecting the randomized controlled trials (RCTs) of using NAC combined with conventional drugs like ambroxol hydrochloride, montelukast or placebo (treatment group) and simply using the conventional drug alone as above conventional drugs (control group) for treatment of chronic bronchitis, and the therapeutic effects were compared between the two groups. The main indicators were total effective rate, lung function indexes [forced vital capacity (FVC), percentage of forced expiratory volume in one second (FEV1) / the predictive value (FEV1%)]; the secondary indicator was St. George Hospital Respiratory Questionnaire evaluation score (the SGRQ evaluation score). Document quality evaluation and data acquisition were carried out independently by two researchers. Meta-analysis was performed by using RevMan 5.3 software. A funnel graph was drawn to evaluate the article publication bias. Results There were 7 Chinese and 3 English RCTs, including 1521 patients in the study. The results of Meta analyses showed: NAC could elevate the overall therapeutic efficiency of patients with chronic bronchitis [relative risk (RR) = 1.17, 95% confidence interval (95%CI) was 1.10-1.25, P < 0.00001], FVC [mean difference (MD) = 0.22, 95%CI was 0.02-0.42, P = 0.03), FEV1% (MD = 4.10, 95%CI was 1.02-7.18, P = 0.005) and lower the SGRQ score (MD = -6.32, 95%CI was -10.48 to -2.17, P = 0.003), showing that the therapeutic effects on these aspects in using NAC treatment group were more prominent than those in the control group. The subgroup analyses showed that NAC combined with ambroxol hydrochloride could elevate overall therapeutic efficiency (RR = 1.20, 95%CI was 1.11-1.29, P <0.00001), FVC (RR = 1.18, 95%CI was 0.99-1.41, P = 0.04) and FEV1% (MD = 4.10, 95%CI was 1.02-7.18, P = 0.005), showing that the therapeutic effects on these aspects in using NAC combined with ambroxol hydrochloride group were more prominent than those in the control group; the total rate of therapeutic effect of NAC combined with montelukast was superior to that of the control group (RR = 1.12, 95%CI =1.03-1.22, P = 0.006); NAC combined with placebo in elevating FVC aspect was better than the control group (MD =-0.01, 95%CI = -0.02 to -0.01, P < 0.00001); funnel plots showed that no publication bias was found in the literatures in the study. Conclusion It is shown that NAC for treatment of chronic bronchitis can improve the overall therapeutic efficiency, lower the SGRQ evaluation score and elevate the lung function in FVC and FEV1% aspects, but no effect on FEV1/FVC.
